Went by the dealership yesterday to check on trailer. After talking with shop manager we walked back shop area and he showed me the part that had broke. I thought it was just a little motor, but to my surprise it was the big all thread rod that turns to pull in and push out the slide. Wish I would have taken a picture to post.
He said it had to be a defective part. The mechanic had to take it off and push the slide in by hand. So nothing I could have done to get the slide back in. Part ordered last week and should be completed in time for our Holloween trip.
